Abnormal FIT results are common and do NOT mean that you have cancer. On average, 10-15 percent of people screened with FIT will have an abnormal result and will require additional testing. This does not mean that cancer was found – over 96 percent of people with an abnormal FIT result will be found to not have cancer.

How likely is a positive FIT test cancer?

How serious is a positive FIT test?
Abnormal or Positive Results
An abnormal or positive FIT result means that there was blood in your stool at the time of the test. A colon polyp, a pre-cancerous polyp, or cancer can cause a positive stool test. With a positive test, there is a small chance that you have early-stage colorectal cancer.
How soon after a positive FIT test should I have a colonoscopy?
Delays to colonoscopy of over 9 mo after positive FIT were significantly associated with higher incidence of CRC and advanced stage of CRC at diagnosis (compared with performing colonoscopy within 1 mo). AOR, adjusted odds ratio; CI, confidence interval; CRC, colorectal cancer; FIT, fecal immunochemical test.
Does a high FIT test mean cancer?
Your doctor might call this FIT positive. This doesn't mean that you have cancer. Blood in your poo can be caused by cancer or by other medical conditions. You usually have a test to look at the inside of your large bowel.
